From be02ef96aa89a6af554a622f266d700ac0c98fdf Mon Sep 17 00:00:00 2001 From: Joey Hess Date: Fri, 11 Apr 2014 01:19:05 -0400 Subject: propellor (0.3.0) unstable; urgency=medium * ipv6to4: Ensure interface is brought up automatically on boot. * Enabling unattended upgrades now ensures that cron is installed and running to perform them. * Properties can be scheduled to only be checked after a given time period. * Fix bootstrapping of dependencies. * Fix compilation on Debian stable. * Include security updates in sources.list for stable and testing. * Use ssh connection caching, especially when bootstrapping. * Properties now run in a Propellor monad, which provides access to attributes of the host. # imported from the archive --- Propellor/Property/Cron.hs | 32 ++++++++++++++++++++++++++++++++ 1 file changed, 32 insertions(+) create mode 100644 Propellor/Property/Cron.hs (limited to 'Propellor/Property/Cron.hs') diff --git a/Propellor/Property/Cron.hs b/Propellor/Property/Cron.hs new file mode 100644 index 00000000..fa6019ea --- /dev/null +++ b/Propellor/Property/Cron.hs @@ -0,0 +1,32 @@ +module Propellor.Property.Cron where + +import Propellor +import qualified Propellor.Property.File as File +import qualified Propellor.Property.Apt as Apt + +type CronTimes = String + +-- | Installs a cron job, run as a specificed user, in a particular +--directory.
